#GIA Winter 2017 Gems & Gemology Explores Cullinan-Like Diamonds, Gem Carvers and Research Developments

Winter 2017 Gems & Gemology Explores Cullinan-Like Diamonds,
Gem Carvers and Research Developments
Includes a full-color wall chart of ruby inclusions

The Winter 2017 issue of Gems & Gemology (G&G), GIA’s (Gemological Institute of America’s) quarterly professional journal, explores the deep geologic origins of the world’s biggest and purest diamonds and what they tell us about the earth; the Dreher family of gem carvers of Idar-Oberstein; the first characterization of Australian Akoya cultured pearls; recent improvements in GIA’s reference standards for trace element analysis; and a comparison of two X-ray microradiography detectors. It also contains a wall chart of inclusions in natural, treated and synthetic ruby. The issue is available in print by subscription and in the GIA Store, and digitally – at no cost – on

G&G opens with “The Very Deep Origin of the World’s Biggest Diamonds.” GIA research scientist Dr. Evan Smith, Dr. Steven Shirey of the Carnegie Institution for Science and Dr. Wuyi Wang, GIA’s vice president of research and development, co-authored the cover article. Their work expands on research presented in the December 2016 issue of Science magazine, in which Dr. Smith and a team of researchers uncovered how Cullinan-like, nitrogen-poor “CLIPPIR” diamonds contain inclusions that offer insight into the nature and formation of the Earth’s mantle. The G&G article provides more detail on the key features of these diamonds as well as data on additional samples.

On the cover of the Winter 2017 issue of Gems & Gemology is the 812 ct Constellation diamond. Recovered from the Karowe mine in Botswana in November 2015. At the time of publication, it was the sixth-largest gem-quality rough diamond ever recorded. The size, near absence of inclusions, low nitrogen content, shape and surface texture place it in a special variety known as CLIPPIR diamonds, which are reviewed in the lead article in this issue.

“Gem Virtuosos: The Drehers and Their Extraordinary Carvings” explores the work of a multigenerational family of gem carvers, the Drehers of Idar-Oberstein, Germany. Robert Weldon, Cathleen Jonathan and Rose Tozer of GIA’s Richard T. Liddicoat Library and Information Center focus on the contemporary craft of Gerd Dreher and his son, Patrick, who create elegant gem carvings from high-quality agate and other rough gem materials.

Research by Dr. Laura Otter and coauthors is presented in “Akoya Cultured Pearl Farming in Eastern Australia.” This is the first gemological characterization of Australian akoya cultured pearls using Raman, photoluminescence, FTIR and UV-Vis spectroscopy.

Additional articles cover new developments in industry techniques: Dr. Jennifer Stone-Sundberg’s “Accurate Reporting of Key Trace Elements in Ruby and Sapphire Using Matrix-Matched Standards” and Dr. Stefanos Karampelas’s “Real-Time Microradiography of Pearls: A Comparison Between Detectors.”

The Winter 2017 issue of G&G also features a wall chart on ruby inclusions, the third in a series of charts on gem inclusions. The same team of specialists that created G&G’s Winter 2016 emerald inclusion chart and the Summer 2017 sapphire inclusion chart, led by GIA’s Nathan Renfro and John Koivula, documents a range of internal features found in natural, treated and synthetic ruby. Laminated versions of all three charts may be purchased at the GIA Store.

This and every issue of G&G since 1934, including full articles, lab notes, photo galleries and exclusive video footage, are available at no cost on GIA’s website at

Additional research articles are available at

Print subscriptions and copies of back issues are available at, or by contacting G&G customer service at +1 760-603-4502.

CIBJO Releases Coral Commission's Special Report

from Press Release

CIBJO releases Coral Commission's Special Report, 
calls for campaign to differentiate between 
precious and non-precious coral 

With fewer than two weeks to go to the opening of the 2017 CIBJO Congress in Bangkok, Thailand, on November 5, 2017, the eighth and the final of the CIBJO commissions' Special Reports for this year has been released. Prepared by Vincenzo Liverino, President of the organization's Coral Commission, the report calls for an educational campaign to differentiate between precious coral varieties, which are harvested in a responsible and sustainable manner, and non-precious varieties, some of which are seeing their numbers dwindle as a result of climate change.
"One of the main concerns of the Coral Commission is to make sure that all precious coral in circulation in the marketplace has been harvested and handled in accordance with the applicable regulatory legislation associated with the protection of wildlife. This is being done for the sake of sustainability, a key doctrinal orientation of the UN charter," Mr. Liverino writes.
Precious corals, which are subject to national regulatory legislation, are harvested in strict observance of responsible practices, and should be perceived as sustainable and responsible products, Mr. Liverino notes. But this is not the way things are sometimes portrayed in the media. "There has been for many years a misunderstanding that precious coral species are the same as those endangered non-precious coral species. It must be stressed that, despite sharing a common name, threatened coral species are not used in the jewelry industry," he adds.
"An educational campaign must be undertaken, to properly explain to the environmentally conscious consumer that the corals that have been used as a biogenic gem material in jewellery for millennia are not the ones that studies have shown to be damaged by climate change, posing a serious challenge to the marine ecosystem in many parts of the planet. It must be underlined that we in the precious coral and jewelry sectors share common global environmental concerns with most of the scientific community," Mr. Liverino writes.

Pantone Unveils Color of the Year 2018: PANTONE® 18-3838 Ultra Violet

from Press Release

Pantone Unveils Color of the Year 2018: 

PANTONE® 18-3838 Ultra Violet

Inventive and imaginative Ultra Violet lights the way to what is yet to come

Pantone, a wholly owned subsidiary of 
X-Rite, Incorporated, and provider of professional color language standards and digital solutions, today announced PANTONE 18-3838, UltraViolet, as the Pantone Color of the Year for 2018. A dramatically provocative and thoughtful purple shade, PANTONE 18-3838 Ultra Violet communicates originality, ingenuity, and visionary thinking that points us towards the future.

“We are living in a time that requires inventiveness and imagination. It is this kind of creative inspiration that is indigenous to PANTONE 18-3838 UltraViolet, a blue-based purple that takes our awareness and potential to a higher level,” said Leatrice Eiseman, Executive Director of the Pantone Color Institute. “From exploring new technologies and the greater galaxy to artistic expression and spiritual reflection, intuitive UltraViolet lights the way to what is yet to come.” Complex and contemplative, UltraViolet suggests the mysteries of the cosmos, the intrigue of what lies ahead, and the discoveries beyond where we are now. The vast and limitless night sky is symbolic of what is possible and continues to inspire the desire to pursue a world beyond our own.

Enigmatic purples have also long been symbolic of counterculture, unconventionality, and artistic brilliance. Musical icons Prince, David Bowie, and Jimi Hendrix brought shades of UltraViolet to the forefront of western pop culture as personal expressions of individuality. Nuanced and full of emotion, the depth of PANTONE 18-3838 UltraViolet symbolizes experimentation and non-conformity, spurring individuals to imagine their unique mark on the world, and push boundaries through creative outlets.

Historically, there has been a mystical or spiritual quality attached to UltraViolet. The color is often associated with mindfulness practices, which offer a higher ground to those seeking refuge from today’s over-stimulated world. The use of purple-toned lighting in meditation spaces and other gathering places energizes the communities that gather there and inspire connection.

“The Pantone Color of the Year has come to mean so much more than ‘what’s trending’ in the world of design; it’s truly a reflection of what’s needed in our world today,” added Laurie Pressman, Vice President of the Pantone Color Institute. “As individuals around the world become more fascinated with color and realize its ability to convey deep messages and meanings, designers and brands should feel empowered to use color to inspire and influence. The Color of the Year is one moment in time that provides strategic direction for the world of trend and design, reflecting the Pantone Color Institute’s year-round work doing the same for designers and brands.”

UltraViolet in Fashion
On the runway or the streets, UltraViolet is an enchanting purple that provides a theatrical linkage for both men’s and women’s styles. True to the coupled nature of UltraViolet, created by combining red and blue, UltraViolet lends itself to unique color combinations in fashion and is easier to pair with all colors on the spectrum than one might think. With golds or other metallics, Ultra Violet becomes luxurious and dazzling; with greens or greys, it evokes natural elegance. Similarly, Ultra Violet takes on distinct appearances with different materials. Lush velvets in the color suggest intrigue for evening, but are also unexpectedly modern in athleisure or sneakers. In accessories, jewelry, and eyewear, UltraViolet suggests the complexities of natural gems, textures, and florals.

About the Pantone Color of the YearThe Color of the Year selection process requires thoughtful consideration and trend analysis. To arrive at the selection each year, Pantone’s color experts at the Pantone Color Institute comb the world looking for new color influences. This can include the entertainment industry and films in production, traveling art collections and new artists, fashion, all areas of design, popular travel destinations, as well as new lifestyles, playstyles, and socio-economic conditions. Influences may also stem from new technologies, materials, textures, and effects that impact color, relevant social media platforms and even up-coming sporting events that capture worldwide attention. For 19 years, Pantone’s Color of the Year has influenced product development and purchasing decisions in multiple industries, including fashion, home furnishings, and industrial design, as well as product packaging and graphic design.
